(Instead of just calling __next__() all the time!) How to Use a Generator as an Iterator Iterators in Python are essentially functions that can be looped over. All generators are iterators, but not all iterators are generators. The finer points of iterators are not in the scope of this...
Using Generators Introduced with PEP 255, generator functions are a special kind of function that return a lazy iterator. These are objects that you can loop over like a list. However, unlike lists, lazy iterators do not store their contents in memory. For an overview of iterators in Python...
Because generators are also iterators—namely, generator iterators—you can alternatively use the collections.abc.Iterator type instead of Generator as a type hint to convey a similar meaning. However, because you won’t be able to specify the send and return types using a pure Iterator type ...
When dealing with large datasets, generators offer a memory-efficient alternative to storing data in lists, tuples, and other data structures that require space in memory for each of their elements. Generator functions can also create infinite iterators, which are not possible with eagerly evaluated...
Python offersrandommodule that can generate random numbers. These are pseudo-random number as the sequence of number generated depends on the seed. If the seeding value is same, the sequence will be the same. For example, if you use 2 as the seeding value, you will always see the followin...

Added support for PySide2 on Python version before 3.6, because the patched code needs no workarounds. Fixed in 0.6.14.3 already. Windows: Convert images to icon files on the fly. So now you can specify multiple PNG files, and Nuitka will create an icon out of that automatically. macOS...

Many of the tools in Python consume iterators." — Raymond Hettinger (source)Recently, Clojure added transducers to the language, which is a concept pretty similar to generators in Python. (I highly recommend watching Rich Hickey's talk at Strange Loop 2014 where he introduces them.)...
